Core crushing and dynamic response of sandwich steel beams with sinusoidal and trapezoidal corrugated cores: A parametric study
Source abstract
Abstract
This paper presents a finite element based parametric study of the dynamic response and strength of sandwich steel beams with either sinusoidal or trapezoidal corrugated core subjected to impulsive blast loads. The sandwich steel beams consists of flat top and bottom substrates made of Steel 1018 and four core layers of Steel 1008. The core layers are arranged with uniform and non-uniform thicknesses. The finite element model is validated with a set of shock tube experiments and thus makes it feasible for a present parametric design study of core configurations. Sinusoidal and trapezoidal core shapes as well as various core thickness arrangements are taken into consideration for comparing core crushing and buckling behavior and their performances in mitigating blast load effects onto the main structure. A unit-cell beam and a fully clamped sandwich beam are studied to elucidate the effect of core shapes and arrangement onto its dynamic response.
